I really don't care and was over it when Cal said he wasn't playing early in the spring semester.
Cal knew, Sharpe knew, his parents knew, and the only people that didn't know were those that pretended not to know or believed Cal.
The bottom line though is that he'd have been somewhere else practicing and taking someone else's developmental minutes, but also making better those he played against in practice. Is it unethical? Sure. Is it selfish? Sure. Other than that, clicking on links about Sharpe or talking about it on social media as a UK fan is rewarding the unethical behavior.
Tune it out
